Application filed August 16, 19%. Serial No. 732,551.

Ton-ll whom it may concern:

Be it known that I, Josnrrr l. HAMMON, a citizen of the United States, residing at Crossett, in the county of Ashley and State of Arkansas, have invented new and useful Improvements in Automatic Log-Car Stakes, of which the following is a specification.

The object of my said invention is the provision of an efficient automatic log car stake.

v To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specificationz- Figure 1 is a side elevation showing the preferred embodiment of my invention with the retaining member in working position.

Figure 2 is a similar view with the retaining member in releasing position.

Figure 3 is a vertical section taken in the plane indicated by the line 33 of Figure 1.

Figure 41 is an enlarged detail side clevation of the lever member of the stake.

Figure 5 is a section through the said lever member on the line 5-5 of Figure 41.

Figure 6 is a detail perspective of the stake body.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel stake comprises a body shown in detail in Figure 6 and formed of appropriate metal. The said body includes a plate-like or flat major portion. 1, apertured at 2 and 3 and provided with a stop flange A and a comparatively long upper flange 5 and also provided with an arm 6 which is arranged in parallelism with the flat major portion 1 and is provided at 7 with a transverse aperture in coincidence with the aperture 3 in the portion 1.

The apertures 3 and 7 of the stake body are for the reception of a pintle 8 through the medium of which the retaining member 9 is pivotally connected at an intermediate point of its length to the stake body. The

said retaining member 9is preferably beveled at 10 and 11, and it will be noted that the said retaining member 9 is strongly held between the arm 6 and the flat major portion 1 of the body, and that said member 9 is adapted in both of the positions shown in Figures 1 and 2 to bear against the body flange 5.

In addition to the elements named the stake comprises a curvilinear lever member 12 pivotally connected to the stake body by a pintle 13 which is appropriately secured in the body aperture 2.

Manifestly in the position shown in Figure 1 the lever member 12 will operate to strongly retain the retaining member 9 in the upright position shown in Figure 1, while when said lever member 12 is shifted to the position shown in Figure 2 the retaining member 9 will be free to gravitate to the position shown in Figure 2. It will also be manifest that when the retaining member 9 is swung from the position shown in Figure 2 to that shown in Figure 1 the beveled end 10 of the retaining member 9 will ride past the outer end of the lever member 12, and will be automatically locked by said member 12 in the upright working position.

By comparison of Figures 1 and 2 it will be noted that the inner arm of the lever 12 is movable between the inner end of the flange 5 and the stop flange 4; also, that when the inner arm of the lever member 12 is swung upwardly it will bring up against the flange 5 while when said lever member 12 is cooperating with the retaining member 9 for the purpose stated, the said lever member 12 will rest on and be supported and braced by the stop flange 4.

It will be also be apparent from the foregoing that my novel log car stake is compact and strong in construction, and is therefore, well adapted to withstand the rough usage to which log car stakes are ordinarily subjected.

Manifestly my improved stakes are adapted to be operated from the side of a log car opposite to where the logs are being unloaded.

Having described my invention, what I claim and desire to secure by Letters-Patent,

1. A log car stake comprising a body having a major portion and an arm in parallelism to said major portion and also hav ing an upper comparatively long lateral flange and a lower stop flange, a retaining member pivotally connected at an intermediate point of its length between the major portion and the said arm of the body and having a beveled heel, said retaining member adapted in upright position to bear against the outer end of the upper long body flange, and a lever member of curvilinear form pivotally connected to the body and arranged to cooperate with the beveled. heel of the retaining member and having a comparatively long arm movable between the said flange of the body.

2. A log car stake comprising a body having upper and lower spaced stops, a retaining member pivoted on said body outwardly beyond said stops and having a beveled heel end, and a lever member pivoted to the body and having a short arm for cooperation with said retaining member and also having a long gravitational arm normally resting on the lower stop and movable between the stops.

In testimony whereof I afiix my signature.

JOSEPH N. HAMMON.
